Dear all,
I just happen to read an article that sheds some light on the re-training
of muscles, "The complementary role of the planatr flexors, hamstrings and
gluteus maximus in the control of stance limb stability during gait." (by
Jonkers et al., Gait & Posture 17 2003, p. 264-272).
The abstract goes like this:
This paper focusses on the contributions of the gluteus maximus, biceps
femoris, gastrocnemius and soleus in maintaining the stability of the
stance limb in the sagittal plane during the midstance of gait. In the
absence of any one of these muscles, the porential compensatory changes in
muscle activation are explored, the aim being to restore stability to the
stance limb. The investigation was carried out by integrating
muskuloskeletal modeling, forward simulation and optimization techniques.
We concluded that the maintenance of stance limb stability requires a
subtle interplay of muscle activations. Weakness in a single muscle is
unlikely to be adequately compensatedd for by increasing or decreasing the
actvation level of one muscle alone.
Good thinking and a good weekend to all you,
Bart
